TABLE 3. Comparison a of Neuropathologic Changes in Subjects With and Without Visual Hallucinationsb.
| VH-Negative (n = 121) | VH-Positive (n = 27) | |
|---|---|---|
| NP Diagnosis | n (%) | n (%) |
| AD without LRP | 37 (30.6) | 4 (14.8) |
| AD with LRP | 38 (31.4) | 16 (59.3) |
| LRP without AD | 16 (13.2) | 5 (18.5) |
| No AD or LRP | 30 (24.8) | 2 (7.4) |
a
Fisher’s exact test for r x c tables, p = 0.02
b
Percentage of VH-positive subjects by neuropathologic category: AD without LRP (10% VH-positive), AD with LRP (30%), LRP without AD (24%), no AD or LRP (6%).
Notes: VH: visual hallucination; NP: neuropathologic; AD: Alzheimer’s disease (Braak Stage > IV and CERAD plaque score B or C); LRP: Lewy-related pathology.(classic Lewy bodies or abnormal Lewy inclusions or neurites).
